The use of bio-test in the disinfestation of food industries

Abstract: In 2012 were given to several Pest Control Companies 387 bio-tests. The treatments were carried out in mills and food industries with sulphurilfluoride or with hot air (heat treatments). The species employed in the bio-tests were Tribolium confusum, Ephestia kuehniella, Plodia interpunctella, Sitophilus oryzae and Lasioderma serricorne. In 19 cases survival was recorded. In these few cases localized treatments with pesticides became indispensable.
